“…In that context, urban built-up structures could be understood as complex social-ecological systems (Moffatt & Kohler, 2008). The study of Tiwary and Kumar (2014) highlights that to understand the urban microenvironment, an integrated assessment of green and grey infrastructure is needed. Moreover, scale issues need to be considered for both the social and the ecological subsystem (Moffatt & Kohler, 2008;Müller et al, 2010b;Scholes et al, 2013).…”

There is a rapidly growing body of literature on the theory about the ecosystem service concept and the practical assessment of ecosystem services in different contexts ranging from natural to urban environments. Yet, where does the concept reach its limits? This paper critically reflects the application of the ecosystem service concept in urban environments illustrating the handling of urban structures (incl. built-up areas) and the risk that the normative principle of the concept could be missed. It is shown that in theory urban structures refer to a variety of ecosystem concepts. As a starting point for ecosystem service assessments, these could be classified into natural, managed, constructed and overbuilt systems. Since ecosystem service concepts do not directly refer to a specific ecosystem definition, but to biophysical structures and processes, all of these classes could be included. However, the dependency on context and scale makes a differentiation in practical ecosystem services assessment challenging. We conclude that the ecosystem service concept does not reach its limits in urban environments, but urban environments represent an extreme case characterized by multifunctionality and a high degree of modification that enables to uncover research challenges applying in any environment. There is a need for a more transparent reporting of theoretical and methodological assumptions to facilitate the comparability between ecosystem service assessments. Comprehensive approaches that consider multiple ecosystem services and include human input, human modification, the ecosystem status as well as their interactions are required to understand the spatial relations between ecosystem services delivered by different ecosystems.

“…Personal exposure to a large fraction of these pollutants occurs during individual commuting Kumar, 2014, 2015;Knibbs et al, 2011), which is associated with adverse health impacts for both urban inhabitants (Pope et al, 2009) and built infrastructure (Kumar and Imam, 2013;Tiwary and Kumar, 2014). Airborne particulate matter (PM), including very small ultrafine particles (UFP, <1 mm) are such pollutants sourced from vehicles' exhaust emissions (Kumar et al, 2010), and has made the issue of air pollution exposure in cities worldwide even more challenging .…”

“…Improved plant growth and leaf area will also enhance other urban ecosystem services such as heat regulation [71], buffering capacity or the absorption capacity for wastes and emissions [72,73], and carbon sequestration [74]. These ecosystem services would partially moderate the worsen heat stress and air pollution in urban areas under the future scenarios [75][76][77][78][79]. It is noteworthy that the wealthy population living in the mesic residential areas may enjoy more benefit from the enhanced ecosystem services than the poorer population living in the xeric residential areas, because the NPP of the mesic ecosystems (lawns and urban forests) would increase much more quickly than the xeric ecosystems (dry shrubs and grassland) (Figures 4 and 5).…”

Abstract:Urban vegetation provides ecological services that promote both the ecosystem integrity and human well-being of urban areas, and thus is critical to urban sustainability. As a key indicator of ecological health, net primary productivity (NPP) provides valuable information about the performance of urban ecosystem in response to the changes in urban climate and atmosphere in the 21st century. In this study, a process-based urban ecosystem model, HPM-UEM (Hierarchical Patch Mosaic-Urban Ecosystem Model), was used to investigate spatiotemporal dynamics of urban ecosystem NPP in the Phoenix city, AZ under three representative concentration pathway (RCP2.6, RCP4.5 and RCP8.5) during the 21st century. The results indicated that, by the end of the 21st century, the urban ecosystem's NPP would increase by 14% (in RCP2.6), 51% (in RCP4.5) and 99% (in RCP8.5) relative to that in the late 2000s, respectively. Factorial analysis indicated that CO 2 fertilization effect would be the major driver of NPP change, accounting for 56-61% of the NPP increase under the scenarios. Under the RCP2.6 scenario, the strongest NPP increase would be found in the agricultural lands located in the west and southeast of the city. Under the RCP4.5 and RCP8.5 scenarios, the strongest NPP increase would be found in the mesic residential areas that mainly located to the eastern, southern, and southwestern of the Phoenix Mountains Preserve. Although higher ecosystem NPP in the future implies improved ecosystem services that may help to alleviate the heat stress (by providing more shading) and air pollution in the city, this will be at the cost of higher irrigation water usage, probably leading to water shortage in the natural ecosystems in this arid region. Furthermore, this study indicated the rich (such as in mesic residential area) would enjoy more benefits from the improved urban ecosystem services than the poor (such as in xeric residential area).
